Building compliance for developers
Developers: build compliance into the programme
A development can reach practical completion with rooms finished but evidence still missing. Treat calculations, inspections and final reports as programme activities with named owners. Start with the building uses, plot schedule, planning decision and proposed construction. These establish the questions to ask before anyone books a site visit.
National Building Compliance provides one contact for the tests, calculations and reports your project needs in England. Tell us the scope once. We identify the relevant services, arrange accredited, qualified assessors and coordinate reports for Building Control and planning officers. The aim is evidence that can be accepted first time, supported by accurate drawings and site information.
Developers: decisions and evidence at each stage
Acquisition and feasibility
Separate existing-building risks from the proposed development scope. Record neighbouring noise sources, intended uses and retained construction. Planning requirements differ by council; check the decision and local information requirements against planning application guidance. A noise survey can inform layout before the site plan becomes expensive to change.
Design coordination
Commission SAP calculations for the domestic energy assessment route described by government SAP guidance. Confirm the appropriate route for non-domestic areas separately. Coordinate fabric, heating and ventilation assumptions. Approved Document O gives guidance on overheating in new residential buildings; consider overheating assessments while window sizes and layouts remain adjustable.
Procurement and construction
Issue a single agreed specification to buyers, designers and subcontractors. Track substitutions for insulation, glazing, junction details and ventilation equipment. Approved Document L provides energy-efficiency guidance, while Approved Document F addresses ventilation. Changes to either system can affect the assessment assumptions and should reach the assessor before completion.
Testing and handover
Build a plot-by-plot readiness schedule for air tightness testing, sound insulation testing and ventilation testing where applicable. Sound testing scope should follow the project route under Approved Document E. Leave room for investigation, remedial work and reassessment rather than treating every first visit as guaranteed closure.
Developers: match the package to the site
| Project situation | Useful service combination |
|---|---|
| Repeated house types across a phased site | Use the New Build Compliance package as the starting scope. Maintain a type register and a separate plot register so design evidence does not get confused with completed-building evidence. Agree how revisions flow between both registers. |
| Flats with shared construction details | Coordinate acoustic design, energy calculations and testing access together. Repeated details deserve early scrutiny because one unresolved junction can affect several homes. Record which drawings and construction details each report assesses. |
| Mixed residential and commercial space | Discuss SBEM calculations for non-domestic areas using the National Calculation Methodology. Keep the residential and commercial evidence schedules distinct, even when procurement and site access are shared. |
| Planning evidence alongside technical design | Consider energy statements alongside calculations. Planning requirements differ by council, as reflected in planning application guidance. Confirm the required submission before ordering a report against a generic brief. |
Developers: information that prevents repeat work
- Provide the current drawing register, unit references and issue dates. Mark superseded information clearly so assessments do not combine incompatible designs.
- Name the person authorised to approve technical assumptions and the site contact responsible for test readiness. These are often different roles.
- Keep product substitutions, photographs and installation records against the relevant plot. A central folder needs a usable naming convention, not just more documents.
- Identify who will receive each final report and who will respond to comments. Agree a visible status for draft, awaiting information and final evidence.
Developers: guides for project meetings
Scope and coordination
- New Build Compliance Checklist
Use the new-build checklist to set an initial agenda with the design team, then turn relevant items into named programme actions.
- SAP vs SBEM: Which Does Your Building Need?
Compare the domestic and non-domestic assessment routes before briefing an assessor on a mixed-use scheme.
- How to Pass a Sound Insulation Test
Share preparation guidance with the site team so acoustic testing is discussed before finishes conceal construction details.
Developers: control the evidence release
Before a phase is handed over, reconcile the report schedule with the actual units being released. Check addresses, plot references and drawing revisions together. A technically sound report can still create avoidable queries if its description no longer matches the sales or site records. Ask the project administrator to flag missing attachments and unresolved comments, while the technical lead checks assessment assumptions. Keep those checks separate so administrative completeness is never mistaken for technical agreement. This also gives the next phase a clear record of decisions that can be reused or need reconsideration.
Developers: procurement questions
Can we appoint one contact for a phased development?
Yes. Provide the whole-site schedule and identify the next release. We can coordinate the service scope around phases while keeping individual plots and report references clear.
Does every project need every package service?
No. The package is a starting point for scoping. Building type, design, construction route and existing evidence determine which services should be included.
What if a test identifies a problem?
Ask for the findings to be linked to the affected location and share them with the relevant contractor. Agree remedial work and any further assessment before updating the handover tracker.
Can you guarantee approval?
No approval outcome should be promised. Assessors prepare evidence for the agreed scope, but the receiving authority considers that evidence alongside the wider project submission.
